WILLIAM REYNOLDS, or NEW YORK, 11. Y;

VIBRATION-ELIMINATOR.

ToaZZ whom it may concern: Be-itknown that I, VILLIAM REYNoLns, g

a citizen of the United State residing at l New York, in the county and State of New my co-pending application, #725,134 filed j is to restore itselfto its natural shape and October 11, 1912, and constitutes an improvement of the invention disclosed in that application. 1

Under certain conditions especially where a cushion of some material rigidity is interposed between members extending from the running'gear and body of a=veh1cle it is found that some of the members when subjected to severe shocks move away from the cushion, so that on the rebound there is some relative movement between the running gear and body which is not under all Ofthere'sistance of the cushion and it is the primaryobject of my invention to oppose continuously all movement in either direction-'andhowever minute by the ever present resistance of a cushion of that character which will not set up independent vibrationsf'of its own. One means by which I attain this primary object is by" distorting the cushion from its-natural shape and when in a'distortedcondition and under tension dispose the' same between the body and running gear of the vehicle so that any relative movement between the body and run-' ning gear will be continuously resisted; by the cushion. The tendency of the cushion the parts of the same in moving into their natural position have no'tendency to go beyond this position, and for this reason I place the cushion under an initial distortion so that it will be forced beyond its natural shape but all action will take place when the cushion is in distorted COl'ldltlOIl.

The various particular objects of the invention will be more fully set forth in the following description of one form of vibra tion eliminators embodying my invention, which consists in the new and novel features Specification of Letters Patent.

Application filed June 2, 1913.

of construction and combinations of parts hereinafter set forth and claimed.

Pitten'ted Feb. 24', 1914.

Serial umvraee.

.In the accompanying drawings: Figu re-.-1 is a longitudinal view through the rear axle of-a vehiclelooking-toward one of-thewheels and showinga preferred-form of my invention mounted inplace. Fig.v 2 is a rear elevation of the device shown inFig. 1 and, Fig. 3 is a longitudinal vertical sectional view taken through the cushion shown-in Figs. 1 and 2 and taken on the linc"3 -:3 of Fig. l.

Describing the embodiment'illustrated the body 1 of the vehicle is resilientlysupported from the running gear 2- by: asuitable-suspension such as the spring 3 and'as the invention is adapted to be applied to the usual form of vehicle, this runninlg-gear ma include either the rear or driving ax eas shown in Fig. 2, with obvious mechanical adaptations may include the front or-steering aide, or the wheel shown may be mounted onthe usual steering spindle.

interposed in any suitable position to be acted upon by the relativemovelnent of body and running gear is ahollow cushioir i, which in this disclosure is shown to bee rounded end cylinder preferably having slightly flattened sides, whichis filled-with compressible fluid such as air.

Extending from the body 1 is a bracket 6 having vertically spaced ledges 7- and 8, the ledges 7 being spaced apart horizontally and the ledge 8 being disposedin a line thercbetween. Affixed to theaxle or other portion of the running gear is a similar bracket 9 having horizontally spaced ledges 10 in vertical alinement opposite-the ledges 7 and an'intermediate ledgell disposed between the ledges 7 and'oppositethe ledge 8. WVith the normal oad of the vehicle the ledges 7 and 10 are so spacedapartthat the cushion 4 fits therebetween, preferably under slight compression, but the ledges 8 and 11 are positioned, in this disclosure, a-distance apart less than the normal depth ofthe cushion 4 at this'place. This disposition of ledges provides a means for retaining. the cushion in place even though a puncture or other accident, cause the same to become collapsed.

At present the cushion is inserted in place between the ledges 7 and 11 and the ledges 10 and 8 before the cushion is blown u and then air is pumped into the same untll the desired tension and distortion is obtained. This tension will act on the ledges 8 and 11 than is necessary to the movement in the op-' posite direction the ledges which check this upward shock are of materially greater cushion engaging area than the ledges which oppose the shock in the opposite direction.- Another advantage of this relatively broad engagement is that it tends to prevent the spring 3 from losing its tension when one of the pairs of wheels is shot by the action of the spring into a depression in the road as this broad bearing engages a material area of the'cushion to support the running gear relative to the body.

In operation any movement of the running gear to or from the body will cause either the ledges 7 to approach the relative stationary ledges 10, compressing the cushion therebetween and permitting the ledge 8 to approach the plane of the ledges 10, or this movement will cause the ledges 10 to move toward the relatively stationary ledges 7 permittingtheledge 11 to approach the plane ofthe ledges 7, or both of these actions will take place simultaneously. It will be noted however that the ledges S and 11 are continuously in engagement with the cushion due to the fact that the cushion is always distorted at this place from its natural position, and this distortion is greater than any possible recovering movement between running gear and body.

By means of this construction I believe that I am the first to eliminate vibrations in a vehicle and to rollover irregularities in the road rather than bounce over them and my invention is broadly drawn to this imrovement.

While one form of the invention has been illustrated and described it is obvious that various other modifications within the skill of the mechanic may be made in the construction herein shown and described without departing from the spirit of the invention, provided themeans set forth in the following claims be .employed.

Having thus described my invention, I claimz+ 1. In combination with members carried by therunning gear and body of. a vehicle, of a. pneumatic cushion distorted from its normal shape, disposed between said members andcontlnuously in engagement therewith, said members continuously'positioned apart a distance less than the normal depth ofthe portion of the cushion between said members whereby any relative movement between the running gear and vehicle will be opposed by said cushion while in distorted condition.

2. In combination with the body and running igear of a vehicle and a resilient suspension or the same, of a cushion disposed between said body and running gear cont-inuously opposing all relative movement between said body and running gear, said cushion beingunder a tension and continuously acting on said resilient suspension to maintain the same under tension.

3. In combination with the body and running gear of a vehicle, a pneumatic cushion, members fixed to the body and running gear engaging the top and bottom of said cushion, to oppose movement of the running gear to and from said body, the member opposing the movement away from said body having a greater cushion engaging area than the cushion engaging area of the members opposing motion in the opposite direction.

t. In combination with members carried by the running gear and body of a vehicle, said members having a limited movement toward and from each other, of a cushion disposed between said members and continuously in engagement therewith, the portion of the cushlon between said members being initially compressed a distance reater than the maximum travel of the mem ers relative to each other and held in distorted condition by said members, whereby any relat've movement between the running gear an body of the vehicle will be continuously opposed by a cushion distorted from its normal configuration.

In witness whereof I my hand in have hereunto set the presence of two witnesses.
